Will I pay CGT if I run my business from home and sell the house?

Possibly. If any part of your home was used exclusively for business, that part may be liable for Capital Gains Tax (CGT) on sale.

Key Points:

• Principal Private Residence (PPR) Relief covers your main home.
• Business-only areas don’t qualify for full relief.

Example:

• House sold: €500,000
• Bought for: €300,000 + €20,000 in allowable costs
• Gain = €180,000
• 10% used exclusively for business
• CGT on €18,000 × 33% = €5,940

Tip: If the space was also used personally, CGT may not apply. Keep records of how it was used.
